  ADVANTAGE OF THE INVENTION According to this invention, the chemical plant design assistance program which can confirm the design content of a chemical plant simply and intuitively can be provided.

Embodiments of the present invention will be described below with reference to the drawings.
In the embodiment of the present invention, a chemical plant design support program for supporting design of a chemical plant will be described. The chemical plant design support method according to the present invention is the same as the processing steps of the computer operated by the chemical plant design support program, and is therefore included in the description of the processing of the program. A display device is connected to the computer that executes the chemical plant design support program.

  FIGS. 1-5 is a figure which shows the example of a screen displayed on the display apparatus connected to the computer which operate | moves by the chemical plant design assistance program for describing embodiment of this invention.

  First, when a user starts a chemical plant design support program, the computer displays a screen as shown in FIG. The screen shown in FIG. 1 includes a screen 1 for displaying a configuration diagram showing a configuration of a chemical plant to be designed (arrangement and connection relation of each device), and an arbitrary timing of the chemical plant displayed on the screen 1. Screens 2 and 13 (setting confirmation screen) for setting and confirming the operation state of each device in (step), screen 3 for registering the type of operation sequence of the chemical plant, and operation steps and operations of the chemical plant A screen 4 for setting and confirming the sequence type, a screen 5 for setting and confirming the operation state of each device at an arbitrary timing (step) of the chemical plant displayed on the screen 1, and various instructions to the computer Icons 6 to 12 for performing are displayed.

  In this state, when the user selects a template of the configuration diagram of the chemical plant from a menu (not shown), the computer stores in advance a memory (this memory may be an internal memory or an external memory). The configuration diagram data of the registered model is read, and based on the configuration diagram data, the configuration diagram of the chemical plant template is displayed on the screen 1 as shown in FIG. 2, and the chemical plant included in the configuration diagram is displayed. A list of tags and names assigned to each device (ac) to be configured is displayed on the screen 2. According to the configuration diagram shown in Screen 1, a receiving valve a is connected to the chemical inlet, a reaction kettle is connected to the receiving valve a, a bottom valve b is connected to the reaction kettle, and a pump c is connected to the bottom valve b. A chemical plant in which a pump c is connected to a chemical outlet is shown. Here, each apparatus which comprises a chemical plant means the apparatus from which an operation state changes with the control apparatus (program) which controls a chemical plant. Since the reaction kettle is not operated by a machine, it is not included in the device here.

  In addition, the structure of a chemical plant can also be changed in the state of the screen shown in FIG. In this case, the user operates the screen 1 with a GUI program included in the chemical plant design support program. For example, the user selects the acceptance valve a and performs copy and paste to add a new device to the chemical plant configuration. Then, by selecting the added device, pressing the tag change icon 6 and inputting the tag and name of the device, the device is added to the list on the screen 2 by the computer. By performing such an operation, the user can create a configuration diagram of an arbitrary chemical plant. Moreover, although the model is used in the above, it is also possible for the user to create all the configuration diagrams of the chemical plant without using the model.

  When the creation of the configuration diagram is completed, the user sets the operation state of the chemical plant shown in the configuration diagram of the screen 1. First, as shown in FIG. 3, the user inputs “Liquid” as the operation sequence type in the Use Phase column of the screen 3 and “1” in the Mode column. The computer stores the operation sequence type in the memory according to the input content. The mode is for distinguishing between the same phases.

  Next, the user selects a sequence field on the screen 4. The column of the sequence is a pull-down menu, and the phase stored in the screen 3 is included in the pull-down menu. The user selects the “liquid receiving” phase mode “1” from the pull-down menu, and inputs the number “1” in the step field. Thereby, in Step 1 of the liquid receiving phase, preparations for setting how each device is moved (operation state) are ready.

  The receiving valve a and the bottom valve b can take two states of on (open) and off (close), and the pump c can take two states of open (operation) and close (stop). These operating states are set using the screen 2 and the screen 13. The user inputs the operation state (blank, on, off, open, or close) of each device in the Action column of each device on the screen 2. For example, the user inputs “off” in the Action column of the bottom valve b, “off” in the Action column of the receiving valve a, and “close” in the Action column of the pump c. Enter “Ready” in. Then, the icon 7 is pressed to instruct the computer to register the operation state in step 1. In response to this instruction, the computer stores the contents input on screens 2 and 13 in the memory as the operation state data of each device in step 1 of the liquid receiving phase, and updates the list on screen 5 as shown in FIG. To do. According to the list on the screen 5, in Step 1 of the liquid receiving phase, the bottom valve b and the receiving valve a are turned off and the pump c is closed, and when these preparations are completed, the process can proceed to the next step. Can be confirmed by text. Note that the configuration diagram displayed on the screen 1 and the list on the screen 5 correspond to design drawings that are conventionally used.

  Next, as shown in FIG. 4, the user inputs “liquid feeding” as the operation sequence type in the phase column of the screen 3 and “1” in the mode column. The computer stores the operation sequence type in the memory according to the input content. Then, the user selects the sequence column on the screen 4, selects the “liquid feeding” phase mode “1” from the pull-down menu, and inputs the number “1” in the step column. Thus, in Step 1 of the liquid feeding phase, preparations for setting how each device is moved (operation state) are ready.

  For example, the user inputs “on” in the Action column of the bottom valve b on the screen 2 and sets the Action columns of the receiving valve a and the pump c to be blank. Then, the icon 7 is pressed to instruct the computer to register the operation state in step 1. In response to this instruction, the computer stores the contents input on screens 2 and 13 in the memory as the operation state data of each device in step 1 of the liquid feeding phase, and updates the list on screen 5 as shown in FIG. To do. When the Action column on the screen 2 is left blank, a state in which the operation state of the previous step (in this case, step 1 of the liquid receiving phase) is maintained is registered. From the list of the screen 5 shown in FIG. It can be confirmed.

  The user repeats the same procedure to register the operation state up to step 4 of the liquid feeding phase, and finishes the design of the chemical plant having the configuration shown in screen 1. For example, a screen as shown in FIG. 5 is displayed when the operation state up to step 4 of the liquid feeding phase is registered. When the design of the chemical plant in the configuration diagram shown in screen 1 is completed, the computer stores the configuration diagram data in the configuration diagram shown in screen 1 in the memory in association with the stored operation state data. In other words, the configuration diagram data of the designed chemical plant and the operation state data indicating the operation state of the chemical plant are stored in the memory in association with each other. Data combining the configuration diagram data and the operation state data is defined as chemical plant design data.

  The chemical plant design support program of the present embodiment has a simulation function for reproducing the operation of the designed chemical plant in addition to storing the chemical plant design data using the GUI as described above. Hereinafter, the simulation function will be described.

  FIG. 6 is a diagram showing an operation flow of a computer that is operated by a simulation function of a chemical plant design support program for explaining an embodiment of the present invention. FIGS. 7-11 is a figure which shows the example of a screen displayed on the display apparatus connected to the computer which operate | moves with the simulation function of the chemical plant design assistance program for demonstrating embodiment of this invention.

  First, the user activates a chemical plant design support program and selects a chemical plant (here, the chemical plant designed above) to be simulated. The computer reads the design data of the chemical plant selected by the user from the memory, displays the configuration diagram of the chemical plant selected by the user on the screen 1 based on the configuration diagram data included in the design data, and generates the design data. A list of the operation states of the chemical plant selected by the user is displayed on the screen 5 based on the operation state data included. In addition, the computer displays a configuration diagram on the screen 1 and simultaneously displays a list of tags and names of each device of the chemical plant displayed on the screen 1 on the screen 2 (S1). By these processes, a screen as shown in FIG. 7 is displayed on the display device.

  When the user selects “liquid feeding” from the sequence field on the screen 4 and presses the start icon 8 on the screen shown in FIG. 7, the computer shifts to the simulation mode. When the user presses the skip icon 10 and issues a confirmation instruction for confirming the operation of the chemical plant at an arbitrary timing (in this case, step 1) (S2: YES), in response to this instruction, the computer reads the design data read out. The display contents of screen 1, screen 2, and screen 13 are switched to the contents corresponding to the operation state of step 1 based on the operation state data included in (S3).

  For example, the computer generates configuration diagram data in which the display color of each device included in the configuration diagram displayed on the screen 1 is changed to a color corresponding to the operation state of each device in step 1, and A base configuration diagram is displayed on the screen 1. In the present embodiment, when the receiving valve a and the bottom valve b are on, the display colors of the receiving valve a and the bottom valve b are gray (represented by hatching in the drawing), and the receiving valve a When the bottom valve b is in the off state, the display colors of the receiving valve a and the bottom valve b are white. In addition, when the pump c is in the open state, the display color of the pump c is gray, and when the pump c is in the close state, the display color of the pump c is white.

  The process of S3 will be described in detail. Since only the bottom valve b is turned on in step 1 of the liquid feeding phase, the computer changes the color of the bottom valve b in the currently displayed configuration diagram according to the operation state of on. The configuration diagram data changed to a different color (gray) is generated, the configuration diagram based on this configuration diagram data is displayed on the screen 1, and the contents of the operation performed in step 1 are displayed in the column of the implementation content of the screen 13 Let In the step column of the screen 4, the number 1 of the step currently being simulated is displayed, and on the screen 2, the operation state (Action) of each device at the step currently being simulated is displayed. The screen at this time is as shown in FIG.

  In addition, in the chemical plant design support program of this embodiment, it is also possible to correct the operation state data in each step during the simulation. For example, when the user wants to correct the operation state data in Step 1 of the liquid feeding phase in a state where the screen as shown in FIG. 8 is displayed, the Action column on the screen 2 may be corrected. For example, the user inputs “open” in the Action column of the pump c on the screen 2 on the screen shown in FIG. When the user presses the icon 7 to instruct an operation state change (S4: YES), in response to this instruction, the computer displays the operation state data of Step 1 of the liquid feeding phase stored in the memory on the screen 2. Is updated based on the operation state input to (S5), the list on the screen 5 is updated, and the simulation mode is terminated. By doing so, even if a mistake is found in the operation state of any step during the simulation, the mistake can be corrected immediately, which is very convenient.

  If no change instruction is issued in S4 (S4: NO) and the stop icon 9 is pressed to give an instruction to end the simulation (S6: YES), the computer ends the simulation mode. On the other hand, if no change instruction is given in S4 (S4: NO) and no simulation end instruction is given (S6: NO), the computer proceeds to S2.

  When the user presses the skip icon 10 again to give a confirmation instruction for the next step (S2: YES), in response to this instruction, the computer changes the display color of the pump c in the configuration diagram displayed on the screen 1 to gray. The configuration diagram data is generated, and the configuration diagram based on this configuration diagram data is displayed on the screen 1, and the characters “TM (timer) start” are displayed in the implementation content column of the screen 13, and the transition condition column is displayed. Display “Time UP”. In the step column of the screen 4, the number 2 of the step currently being simulated is displayed, and on the screen 2, the operating state of each device in the step currently being simulated is displayed (S3). The screen at this time is as shown in FIG.

  Further, when the user presses the skip icon 10 to give a confirmation instruction for the next step (S2: YES), in response to this instruction, the computer changes the display color of the pump c in the configuration diagram being displayed on the screen 1 to white. Configuration diagram data is generated, a configuration diagram based on the configuration diagram data is displayed on the screen 1, and the content of the operation performed in step 3 is displayed in the implementation content column of the screen 13. Further, the step number 3 of the screen 4 is displayed in the step column of the screen 4, and the operation state of each device in the step of the current simulation is displayed on the screen 2 (S3). The screen at this time is as shown in FIG.

  Further, when the user presses the skip icon 10 and instructs to confirm the next step (S2: YES), in response to this instruction, the computer changes the display color of the bottom valve b in the configuration diagram displayed on the screen 1 to white. The configuration diagram data is generated, and the configuration diagram based on the configuration diagram data is displayed on the screen 1, and the content of the operation performed in step 4 is displayed in the implementation content column of the screen 13. Further, the step number 4 of the screen 4 is displayed with the step number 4 being currently simulated, and the screen 2 is displayed with the operation state of each apparatus at the step currently being simulated (S3). The screen at this time is as shown in FIG.

  As described above, according to the chemical plant design support program of the present embodiment, the operation of the chemical plant is selected by selecting a chemical plant having a desired configuration, selecting an operation sequence type, and pressing the skip icon 10. Based on the state data, the configuration diagram displayed on the screen 1 is switched for each step. The user can easily and intuitively check the operation state of each device at each step by looking at the configuration diagram displayed on the screen 1, and confirm the design contents while looking at the design drawing on paper. Compared to the conventional method, it is possible to remarkably reduce the time for confirmation.

  If the user presses the icon 12 before modifying the Action column of the screen 2 and issuing a change instruction in the state shown in FIG. 8, the computer changes each of the operation states set on the screen 2. Configuration diagram data in which the display color of the apparatus is set is generated, and a configuration diagram based on the configuration diagram data is displayed on the screen 1. In this case, the same screen as the screen 1 in FIG. 9 is displayed on the screen 1. In the present embodiment, the configuration diagram is simple for simplification of description, but in actuality, the configuration diagram is very complicated. For this reason, it is highly convenient for the user that the operation state can be confirmed on the screen 1 after the operation state is set on the screen 2.

  In addition, when the user presses the icon 12 before inputting the Action column of the screen 2 and pressing the icon 7 in the state shown in FIG. 3, the computer reflects the contents set in the screen 2 on the screen 1. Processing may be performed. In other words, the design contents are visually confirmed by changing the color of each device on the screen 1 according to the state of each device set on the screen 2. The user may check the design contents visually and determine that there is no mistake in the contents before pressing the icon 7. These operations may be performed each time a design content is newly entered in the Action column of the screen 2.
